More than five hundred and fifty questionnaires were distributed, highlighting workers’ preferred digital channels and platforms. The results indicate that the majority use social media through their mobile phones, with WhatsApp being the most popular app, followed by Facebook and LinkedIn. The study reveals that workers use social media for entertainment purposes and to develop professional and social relationships, with 55% unable to live without social media at work for recreational activities. In addition, 35% spend on average 1 to 2 hours on social networks, mainly between 12 p.m. and 2 p.m. It also appears that 46% believe that social networks moderately improve their productivity. These findings can guide marketing strategies, training, technology development and government policies related to the use of social media in the workplace.展开更多

In this paper, the impact of urban agglomeration on labor productivity is explored by making comparisons among these four cities. The model used for analysis is a classical model derived from previous studies. Some indicators, such as population density and economic density, were selected to examine the impact of urban agglomeration on the labor productivity based on the time-series data for the four cities from 1990 to 2007. The four main conclusions are: l) The promotion from the growth rate of population density on the growth rate of labor productivity is limited. 2) The negative relationship exists between the growth rate of employment density and the growth rate of labor productivity. 3) Agglomeration effect exists in the four cities, the highest one is Dalian, Shenyang takes the second place, followed by Changchun and Harbin, and the predominant promotion exerted on the labor productivity is the output density.展开更多

To examine the social factors affecting the current status of the wetlands utilization for agriculture in Nigeda, a simple random sampling technique was used to select 200 farmers cultivating wetlands and a structured questionnaire was applied to elicit the information on the social factors. Data collected were described using frequency and percentage and a multiple regression analysis was used to identify significant variables that are determinants of wetland utilization. The results of the analysis showed that significant variables included crop preferences, farming system, culture, taste, land tenure, knowledge of wetland cultivation, perceived suitability, farmers' tribe, location of wetland, and farmers' age. it was concluded with suggestions for the right combination of policies, public awareness, and appropriate farming methods in order to improve wetland utilization in Nigeria.展开更多

First, it introduces the concept of social production of space, emphasizing the role of social agents in urban processes. Then, it presents specific aspects of the history of Juiz de Fora" its origins and how social agents and forces have played a significant role in shaping the built environment of the city--specially represented by main streets of the city. The paper studies how the social agents, with their different visions and goals, have influenced the process of formation and development of the city. This demonstrates the complexity of the existing relationships between the built environment and the social context that is specific to the city. Different urban forces fight for city spaces, construct and modify its territory so that their needs are fulfilled. Their strength, their experiences and efforts, and their ideas of a city are inscribed in urban landscapes; in similar ways, these are revealed by the city paths we follow here.展开更多

This paper proposes a kind of hardware-software-integrated mediators called social sensors (S2ensors) to facilitate the production interactions among customers, manufacturers, and other stakeholders in the social manufacturing systems (SMS). The concept, classification, operational logics, and for- malization of S2ensors are clarified. S2ensors collect sub- jective data from physical sensors and objective data from sensory input in mobile Apps, merge them into meaningful information for decision-making, and finally feed the decisions back for reaction and execution. Then, an S2en- sors-Cloud platform is discussed to integrate different S2- ensors to work for SMSs in an autonomous way. A demonstrative case is studied by developing a prototype system and the results show that S2ensors and S2ensors- Cloud platform can assist multi-role stakeholders interact and collaborate for the production tasks. It reveals the mediator-enabled mechanisms and methods for production interactions among stakeholders in SMS.展开更多

The quality of Graduate Programmes is often associated with the scientific collaboration. This paper discusses how scientific collaboration processes can be identified and characterized through social and complex networks. For this purpose, collaboration networks of bibliographic production, research projects, and committees of PhD theses and Masters’ dissertations by researchers from a graduate program in computational modeling were studied. The data were obtained from CAPES’ reports of the period from 2001 to 2009. Among the studied indices, centrality indices indicate the presence of prominent researchers who influence others and promptly interact with other researchers in the network. The indices of complex networks reveal the presence of the small-world (i.e. these networks are favorable to increase coordination between researchers) phenomenon and indicate a behavior of scale-free degree distribution (i.e. some researchers promote clustering more than others) for one of the studied networks.展开更多

Humans’ so...This paper investigates the phenomenon of imbalance between the frequencies of the nice and Adj and Adj and nice patterns from the perspective of humans’ social and limited-processing-capacity attributes. Humans’ social attribute requires that language users stay informative with minimal effort in communication, resulting in the from-the-least-to-the-most-informative information organization in discourse. Their limited-processing-capacity attribute requires that they resort to the production biases of "easy first" and "plan reuse" in order to achieve communicative efficiency in real-time production. The analysis of the occurrences of the nice and Adj pattern and native speakers’ judgment of the degree of informativeness of nice in these occurrences suggest that nice is largely delexicalized. Such delexicalization makes nice and Adj consistent with the information organization and allows language users to stay informative with the use of the pattern, thus in line with the social attribute, but not Adj and nice. In the meantime, nice is not only highly frequent but also conceptually salient when it comes to the positive property(Panther & Thornburg, 2009), making nice and Adj easier to produce and more likely to be reused than Adj and nice, thus in line with the limited-processing-capacity attribute. The analysis of the unbalanced frequency of the two patterns suggests that human attributes should be considered when studying language form, and this should offer insights into English learning.展开更多

This work focuses on an analysis of how digital natives carry out image capture, how much time is spent on this activity and what types of images are consumed in different types of social networks. It also examines what type of images are captured and what is done with these images in social networks. The study is applied to a specific sample of 93 university students who have full access to mobile devices, applications and social networks in their daily lives. It provides information as to their behavior within a changing techno-social scene which sees the emergence of new mobile devices, specialized applications and social networks dedicated to photography along with other nascent forms and styles of digital production and socialization. This shall be compared to a previous study carded out in 2010.展开更多

The present research is a conceptual study. The data were collected to analyze the entrepreneurship theories in Saudi Arabia's context. The data related to entrepreneurship spirit, perception of society towards entrepreneurship, and other macroeconomic indicators are collected from different research journals, websites of different corporate houses, and government sources to analyze the social entrepreneurship theories, such as failure thesis, interdependence theories, welfare state theory, supply-side theory, entrepreneurship education, etc.. The theoretical hypothesis of interdependence theory, entrepreneurship spirit, and general education and the theoretical analysis of this paper in light of Saudi Arabia are in line with the theory. But the hypothesis generated out of failure thesis theory, welfare state theory, entrepreneurship education, and individualistic and collective society culture is not in line with these theories.展开更多

Their limited-processing-capacity attribute requires that they resort to the production biases of "easy first" and "plan reuse" in order to achieve communicative efficiency in real-time production. The analysis of the occurrences of the nice and Adj pattern and native speakers’ judgment of the degree of informativeness of nice in these occurrences suggest that nice is largely delexicalized. Such delexicalization makes nice and Adj consistent with the information organization and allows language users to stay informative with the use of the pattern, thus in line with the social attribute, but not Adj and nice. In the meantime, nice is not only highly frequent but also conceptually salient when it comes to the positive property(Panther & Thornburg, 2009), making nice and Adj easier to produce and more likely to be reused than Adj and nice, thus in line with the limited-processing-capacity attribute. The analysis of the unbalanced frequency of the two patterns suggests that human attributes should be considered when studying language form, and this should offer insights into English learning.
文摘The following study shall analyse results of an exploration into production, consumption, socialization, privacy and copyright practices among Mexican university students who take photography through mobile devices in social networks. This work focuses on an analysis of how digital natives carry out image capture, how much time is spent on this activity and what types of images are consumed in different types of social networks. It also examines what type of images are captured and what is done with these images in social networks. The study is applied to a specific sample of 93 university students who have full access to mobile devices, applications and social networks in their daily lives. It provides information as to their behavior within a changing techno-social scene which sees the emergence of new mobile devices, specialized applications and social networks dedicated to photography along with other nascent forms and styles of digital production and socialization. This shall be compared to a previous study carded out in 2010.
文摘More and more UK-based researches begin to focus on the British White population,as they are the main ethic group in UK society that leads and influences the development of UK education and society.According to the UK government figures in 2018,statistics show that“the employment rate of British White stood at 75%,with the overall employment rate in the UK stood at 74%”(UK Government,2018).At the GCSE level in 2018,it is demonstrated that“there are more than 63%of British White pupils who achieved A*to C levels in English and Mathematics exams”(UK Government,2018),higher than the excellence rate of Mixed(30%),Black Caribbean(51%),and Pakistani(58%).It is obvious that British White people are highly prioritized in UK society,especially in educational fields due to the unequal distribution of educational resources between British Whites and other ethnic groups in UK society.However,there are also some of the inequalities that exist among British Whites,as their differences gender,regions,and socio-economic status.This paper aims to have an exploration on the British White education in a further step in terms of how the inequalities exist in their education,primarily from the lens of international education as assimilation,social reproduction,and gender issues.
文摘The present paper discusses the different theories on entrepreneurship in general and social entrepreneurship in particular to investigate the different determinants of social entrepreneurship in the context of Saudi Arabia. The present research is a conceptual study. The data were collected to analyze the entrepreneurship theories in Saudi Arabia's context. The data related to entrepreneurship spirit, perception of society towards entrepreneurship, and other macroeconomic indicators are collected from different research journals, websites of different corporate houses, and government sources to analyze the social entrepreneurship theories, such as failure thesis, interdependence theories, welfare state theory, supply-side theory, entrepreneurship education, etc.. The theoretical hypothesis of interdependence theory, entrepreneurship spirit, and general education and the theoretical analysis of this paper in light of Saudi Arabia are in line with the theory. But the hypothesis generated out of failure thesis theory, welfare state theory, entrepreneurship education, and individualistic and collective society culture is not in line with these theories.

文摘This study takes the virtual business society environment(VBSE)practical training course as a case study and applies the theoretical framework of the context,input,process,product(CIPP)model to construct an evaluation indicator system for the application of civic and politics in professional practice courses.The context evaluation is measured from the support of the VBSE practical training course into course civic and politics,teachers’cognition,and the integration of course objectives;the input evaluation is measured from the matching degree of teachers’civic and political competence,and the matching degree of teaching resources;the process evaluation is measured from the degree of implementation of civic and politics teaching and the degree of students’acceptance;and the product evaluation is measured from the degree of impact of civic and politics teaching.
文摘According to the different products that two upper enterprises produce, this paper analyzes the transfer pricing of intermediate product and the effect of social welfare of vertical merger under imperfect competition market. The conclusions are: the transfer pricing of intermediate product is equal to marginal cost; the perfect outputs that upper enterprises sell to the market before and after the vertical merger of enterprises are the same; the product price in the integrated enterprises may be higher, lower or equal to the price in non-integrated enterprises.
